Abstract

Sugar beet (Beta vulgaris L.) is an important industrial crop cultivated primarily for sucrose production, with
additional applications in livestock feed, bioethanol production and integrated biorefinery systems. Its adaptation to
relatively cool growing conditions makes it a potential complementary sugar crop for selected highland
environments in Kenya. However, its suitability for cultivation in Kabianga, Kericho County, requires assessment of
local soil conditions and crop nutrient requirements. This study evaluated the chemical properties of soil from
Kabianga to identify potential constraints to sugar beet production and propose appropriate soil management
interventions. The assessment was based on soil analytical results from Imara Analytical Laboratories and relevant
agronomic literature. The reported results indicated strongly acidic soil conditions, with a pH of 5.09, and a
phosphorus concentration of 4.07 ppm. Calcium and sulphur were classified as low, while manganese and iron
concentrations were reported as elevated. Nitrogen and organic matter were classified as adequate, and potassium
as high. These findings suggest that soil acidity and nutrient imbalances may constrain crop establishment, root
development and nutrient uptake. However, the interpretation of individual nutrient concentrations requires
confirmation of the laboratory methods, units and reference ranges, particularly for calcium, sulphur,
micronutrients and cation exchange capacity (CEC). Agricultural liming, phosphorus supplementation and targeted
nutrient management are potential interventions for improving soil conditions. Indicative amendment and fertilizer
rates should be confirmed through laboratory lime-requirement testing and crop-specific nutrient recommendations
before application. Field trials are also necessary to evaluate root yield, sucrose concentration, crop maturity and
the effectiveness of the proposed treatments. The findings provide a preliminary basis for investigating sugar beet
cultivation in Kabianga but do not, on their own, establish commercial suitability. Further agronomic and economic
evaluation is required to determine whether the area can support productive and commercially viable sugar beet
cultivation.
